Python| Sympy Line.intersection() 方法

在 Sympy 中，函数intersection()用于查找与另一个几何实体的交集。

Syntax: Line.intersection(o)

Parameters:
 o: Point or LinearEntity

Returns:
 intersection: list of geometrical entities

示例 #1：

# import sympy and Point, Line
from sympy import Point, Line
  
p1, p2, p3 = Point(0, 0), Point(1, 1), Point(7, 7)
l1 = Line(p1, p2)
  
# using intersection() method
showIntersection = l1.intersection(p3)
  
print(showIntersection)

输出：

[Point2D(7, 7)]

示例 #2：

# import sympy and Point, Line, Segment
from sympy import Point, Line, Segment
  
p1, p2, p3, p4 = Point(0, 0), Point(1, 1), Point(0, 5), Point(2, 6)
l1 = Line(p1, p2)
s1 = Segment(p3, p4)
  
  
# using intersection() method
showIntersection = l1.intersection(s1)
  
print(showIntersection)

输出：

[]
